The aim of the study was to investigate the effects of Arabic gum (AG) coating, UV-C illumination and its combinations on postharvest quality parameters of cocktail tomatoes (Solanum lycopersicum L. cv. Ipekce FThe highest titratable acidity (TA), total soluble solids (TSS) and the lowest weight loss were obtained in AG20 treatments. Maximum fruit firmness and L* value were in AG20 and UV-C+AG20 treatment. The greatest h° values were recorded in AG20, UV-C+AG20 and control group. The highest vitamin C content were obtained from AG20, UV-C+AG10 and UV-C+AG20 treated tomatoes. Minimum lycopene content was determined from AG10, AG20, UV-C+AG10 and UV-C+AG20 treatments. Maximum chlorophyll content was determined from UV-C+AG20-treated tomatoes. AG10, AG20, UV-C+AG10 and UV-C+AG20 treatments resulted in lower ethylene emissions as compared to control and UV-C-treated tomatoes. AG20, UV-C+AG10 and UV-C+AG20 treatments generally had lower values than control and UV-C in term of respiration rates.It is concluded that AG20 treatment effectively maintained the postharvest quality and biochemical properties of cocktail tomatoes as compared to other tested treatments. © 2021 Society of Chemical Industry. |
